THREADING-TOOL.

SPECIFICATION forming part of Letters Patent No. 696,299, dated March25, 1902.

Application filed November 27, 1901- Serial No. 83,869. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH E. BAINES, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have inventedor discovered certain new and usefulimprovements in Threading-Tools, of which improvements the following isa specification.

The invention described herein relates to certain improvements inhandles or holders for threading-dies, and has for its object aconstruction whereby the threading-dies may be easily and quicklyinserted in or removed from the holder; and it is a further object ofthe invention to provide forthe separation of the body portion of theholder from its handles, thereby rendering the same capable of compactarrangement for transportation.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a plan View of my improved holder, and Fig. 2 is a sectionalelevation of the'same.

In the practice of my invention the body portion 1 of the holder isprovided with angular notches or recesses 2, oppositely disposed for thereception of the corners of a rectangular block 3, in which thethreadingcutters are formed. A hole or opening whose axis will coincidewith the axis of the circle on which the threading-cutters are made isformed through the body portion 1 and acts as guide for the tool incutting threads on pipes or rods; This hole or opening, which is made ofa diameter adapted to receive the largest pipe to be cut by the tool,can be reduced in size by the employment of thimbles 4, differing inthickness of their walls, as is well understood in the art.

The body portion 1 is formed with short arms or projections 5, arrangedon opposite sides of the body portion, and on these arms are slippedcubes 6,'fitting the arms or projections closely and formingoperating-handles. These auxiliary or tubular handles 6 are providedwith suitable means whereby when slipped in position they will hold thedie-block 3 securely in its seat or recesses. A

convenient form of lock consists in forming extensions or fingers 7 onthe tubular handles, said extensions being adapted when the handles areplaced in position to bear upon the block, and thereby hold the samefirmly in its seat in the body portion.

It will be observed by reference to Fig. 2 that the removable thimbles 4are so arranged in the holder 1 as to be locked in position by the blockor die 3, so that the lock, whereby the block or dieis held in position,also serves to lock the thimble in position.

It will be readily understood by those skilled in the art that thisconstruction permits of the packing of a complete threading tool in asmall space convenient for storing or transportation.

I claim herein as my invention 1. In a cutting-tool the combination of abody portion provided with seats for the re ception of a threading blockor die and a guide-thimble, removable handles and a lock operative by ahandle when adjusted to position on the body portion for securing theblock and thimble in position in said seats, substantially asset forth.

2. A cutting-tool in combination with a body portion provided with. arecess for the reception of a cutting or threading block and havinglaterally-extending arms or projections, and auxiliary handles adaptedto fit over the arms or fingers and provided with means for locking theblock in position, substantially as set forth.

3. A cutting-tool having in combination, a body portion provided with arecess or seat for the reception of a cutting-block and havingdiametrically-arranged arms and tubular handles adapted to fit over thearms and provided at their inner ends with fingers or extensions adaptedto bear upon the block when arranged in its seat, substantially as setforth. In testimony whereof I have hereunto set my hand.

JOSEPH E. BAINES.
